Until recently, user email address and password did not need to be entered every time the iIPhone launched. Now every session requires the cumbersome entry of email address and password (made even more cumbersome by fact the app wasn't designed to accommodate iOS keyboard shortcuts and the app needs to be logged in to whenever the phone screen is revived while casting the video to a chromecast or apple tv). Extremely annoying to the point of unusable.
How to fix this problem? How to enter username and password permanently once and only once.
